Is it possible to become a witness without going back to 0.9.3 keys?

[wmbutler]

All,

I'm ready to be a witness. I'm running xeroc's docker container for the full node without RPC. Is there a way to do this without going though the 0.9.3 key process? I have a 2.0 wallet with a number of accounts that I could use as a witness. Thanks for any help you can provide.
